WIRE REDUCER.

Application filed September 9, 1926. Serial No. 134,463.

This invention relates to animproved apparatus which may be briefly a wire reducer.

The invention has more particular reference to a means for rolling and reducing. wire rods before they are subjected to the drawing operation.

The particular details of construction forming the novelty of the device will become apparent during the course of the foll0 lowing descriptions and from the drawings.

In the drawings:

Figure 1 is a side elevation showing :1 diagrammatic illustration of the arts,

Fig. 2 is also a diagrammatic view look- 1 ing down upon the top of the apparatus,

' Fig. 3 is a side elevation of the reducing and shaping rolls and supporting means therefor,

Fig. 4 is a top plan view of Fig. 3,

Fig. 5 is an end view of the same.

In the drawings the reference character 1 designates a tempering furnace of appropriate construction through which the wire rods 2 are passed to subject them to the heat and to render them substantially red hot.

The wire rods are wound upon spools as indicated at 3. After leaving the furnace, the

rods are subjected to the action of the two sets of rollers 4. and 5 respectively. Finally,

39 the wires are wrapped upon suitable receivers as indicated at 6.

As shown in Figs. 3 to 5 inclusive, the pressing rollers are supported on a structure which includes four standards 7 having feet at their lower ends fastened to an a propriate support. The upper ends of t e standards areslotted as indicated at 9 and these standards are connected together by a top connecting bar 10. The lower set of rollers 5, which includes two pairs of rollers, are fixedly mounted upon shafts 11 journaled in suitable hearings in the standards. One shaft is provided with a beveled driving pinion 12 and a sprocket wheel 13. A

5 strip 19 is connected thereto and a screw 20 sprocket chain 14 is trained over this is swivelly connected at its lower end to the central portion of this tie 19. This stem 20 extends up through a bar 21 which is connected to the central portions of the top bars 10 and the upper ends of the same carry a hand wheel 22. Obviously then, the unit comprising the bearing blocks 17, the connection 18, and the two sets of rollers 4 may be moved up and down under the action of the swivelly mounted hand wheel and screw threaded stem. It will be noted that the cooperating peripheral portions of the two sets of rollers are provided with grooves 23 for reception of the wire rods.

In practice, the wire rods are wound first on the spools and pass through the furnace, where they are subjected to a heat of the proper temperature to render them substantially red hot. The red hot wires leave this furnace and then pass between the grooves 17 of the pressing roller, where they are simultaneously reduced in diameter and made as uniform cylindrical cross-sections. The finished wires are then again wrapped upon suitable receivers until it is desiredto subject the same to a subsequent drawing operation.

Under ordinary conditions the wire rods which come from the rolling mills are in a very bad condition. They are not of proper size and are all sorts of shapes. The rods received from the mills are known as soft rods and they then are subsequently subj ected to the tempering action to render them hard. Then, they go to the wire drawers to be drawn and in this operation, specially constructed dies are required because of the inequalities in the metal. My idea is to reduce the wires, to shape them properly and s to simultaneously temper the same before 95 subjecting them to the drawings, whereby to effect a substantial saving in expense and labor. In this connection, I might state that varying sizes of reducing rollers will be provided and the sizes of the grooves in these 100 rollers will vary so that the wire rods may be subjected to successive action for reducing the same very slightly to a greater degree each time they are passed through a rolling apparatus having smaller rollers and grooves.

It is believed that by considering the description in connection with the drawings, a clear understanding of the invention will be had. In view of this, a more lengthy description is thought unnecessary.

Minor changes comin Within the field of invention claimedmay be resorted to if desired.

I claim: v

In an apparatus of the class described, a lurality of standards, a .pair of spaced parallel shafts journalle-d in bearings in said standards, a pair of grooved rollers on each I shaft, said standards being provided above said shaft with slots, bearing blocks slidable in said slots, upper shafts journaled in said bearing blocks, additional grooved rollers carried by said upper shafts, and cooperable with the first-named rollers, bars extending across the top of the standards, connecting 1 members between the bearing blocks, a tie strip between the members, abar between the first mentioned bars, a stem threaded through an opening in the last mentioned bar and engaged with the tie strips, and an adjust- 20 ing wheel at the upper end of the stem. 7 In testimony whereof I aifix my signature.
